What should be noted when replacing the battery of a Mercedes GLE400?
3 Answers
For Mercedes-Benz series models, when replacing the battery, unlike other German cars that require matching, as long as the battery model and ampere-hour rating match, no matching is needed. It is important to note that when installing the battery, the positive and negative terminals must not be reversed. What should be noted when replacing the battery? 1. When replacing the battery, it is necessary to replace it with an AGM battery of the same specifications as the original. If a general battery is replaced, due to different specifications, the engine module may judge the supply voltage as too low, resulting in the inability to eliminate the fault indicator light. (1) If replacing with the power disconnected, first take the key out of the car and wait for 5 minutes to allow the vehicle to enter sleep mode before replacing. (2) If replacing without disconnecting the power, be careful not to let the positive terminal touch the car body during the replacement process, as this may cause other phenomena such as module fault indicators. 2. When connecting the battery terminals, connect the positive terminal first, then the negative terminal. After installation, anti-rust protective agent or acid-free grease can be sprayed on the battery terminals for protection. When the Mercedes ammeter pointer shows insufficient battery charge, it should be charged in time. The battery charge of the Mercedes E-Class can be reflected on the dashboard. Sometimes, if you find the charge is insufficient on the road and the engine stalls and cannot be started, as a temporary measure, you can seek help from other vehicles, using their vehicle's battery to start the vehicle by connecting the negative terminal to the negative terminal and the positive terminal to the positive terminal.
I just replaced the battery of my Mercedes-Benz GLE400 by myself, and safety is absolutely not something to be taken lightly. Before replacing, you must turn off the engine and wear insulated gloves and goggles to prevent electric shock or sparks from causing injury. Mercedes-Benz vehicles have complex electronic systems, and sudden power loss may trigger alarms or damage the computer. Remember the disconnection sequence during operation: first remove the negative terminal, then the positive, to avoid tools touching the metal parts of the body and causing a short circuit. When connecting the new battery after replacement, connect the positive terminal first and the negative last, gently tightening the screws. The battery model should be AGM type, with a capacity of 92Ah to match the original specifications, otherwise, the starting performance will be poor. Personal experience has taught me that improper operation can cause the vehicle to crash, leading to additional expenses for fault handling. Safety first—if you're unsure, it's more reliable to go to a professional shop, saving both worry and hassle.
With years of car experience, the key to replacing a battery is choosing the right specifications. The Mercedes GLE400 requires a dedicated AGM battery, with a capacity of around 92Ah and a standard 12V voltage—parameters must match precisely, or the car won't start. When doing it yourself, check the vehicle manual to confirm the model, and don't cheap out on a regular battery—AGM is more durable. Before installation, test the old battery's low voltage to avoid accidental starts. After installing the new one, ensure terminal connections are tight to prevent corrosion from shaking. A related tip: Mercedes' electronic systems are sensitive; power loss may cause window memory loss, so keep a car power supply handy. For brands, opt for reputable ones like Varta for guaranteed quality. Finally, test-start the car to ensure smooth operation and avoid future hassles.
